I am delighted that you have chosen to take on the role of Keeper of the Grove here. It is imperative that you put a stop to the opportunistic critters in the magical forest from taking the crystals. Develop recognizable nature guardians as a deterrent against the stealing of crystals. You can also create defensive barriers in order to discourage attacks from your enemies on your forest. You are the one who is accountable for the safety of the crystals. To your advantage.
